The pool pictured above is located at the Hanging Gardens Ubud Hotel in Bali, Indonesia. It is a split-level infinity pool made with stone from the area and containing a wall of solidified volcanic ash. Swimmers are suspended high up over treetops of the lush jungle below.

Architect Popo Danes designed the hotel and grounds with the intent to blend in with the contours of the land and existing natural habitat.

The pool's upper level has a spacious deck, which is connected to the hotel bar. The lower level is built for added privacy and is nearly hidden from view. Guests seeking a romantic evening can reserve the lower level of the pool to dine on a floating, wooden deck draped with sheer fabric. From this candlelit deck, the diners are treated to views of an ancient temple in the distance, with nighttime jungle sounds as their "musical accompaniment."

Also, I can't get to David Olkarny's site at the moment because it's under maintenance ("Ce site est en maintenance") :) but I'll check back. The Hanging Gardens Ubud's website calls the pool "without a doubt one of the most photogenic and photographed pools around the globe."
